Period/fertile date has changed??

Nicola • Hi I`m Nicola, 34 I have 2 children 1 son 13 yrs 1 daughter 10yrs. Married for almost 4 yrs & together for 16 yrs!
Hi I've just edited my period for this month as shorter than expected, but now it has changed my fertile week straight after? Plus my next AF is due in 19 days when I have cycles averaging 33 days?! I've tried to edit it, now it won't allow me to do so. I've added pics of June & July......pls help!
